6 Page 6 1 Functional Description 1.1 Overview OPER SIGNAL SET DI ERROR WSS WSS ADJUST WSS: Wide Screen Signalling. A RUBIDIUM module AI/DI/XI with option W decodes these data of line 23 according to the European Standard EN (version: V1.4.1, ). The decoded data can visibly be displayed on a video window. Choose the Rubidium module according to the video system: RUB AI: CVBS analogue video 625/50 (PAL). RUB DI: Digital video channel (SD). RUB XI: Digital video channel (3G, HD, SD). RUB XI additionally can decode WSS data out of an Ancillary Data Packet according to SMPTE 2031 in conjunction with ETSI EN These are the key features of the system: Decoding of the WSS data. The 14 data bits are grouped in 4 data groups: Group 1 Group 2 Group 3 Group 4 Aspect ratio: Full format or letterbox, position. Enhanced services: Camera or film mode, colour code, helper signal. Subtitles: Yes/no and mode. Others: Surround sound, copyright. Four windows are available to display the decoded data in a bit or text format. Each video window can be positioned over the entire screen. Size, brightness, background mask,, can be adjusted. Example for a text format (data group 1): 4:3 FULL FORMAT Example for a bit format (data group 1): GROUP 1: 0001 A description of each individual bit is given in the next chapter. The first bit displayed in the video window corresponds to the LSB, so this example shows b0 b1 b2 b3. GPI outputs are available signalling the state of selected bits. If decoding of WSS data out of line 23 is required, it is recommended to adjust the WSS decoder to your video signal during first installation. Please once perform an Auto Adjust (see chapter Configuration of the RUBIDIUM Module, item 3: WSS Parameter).

10 Page Configuration of the RUBIDIUM Module Upon delivery, the RUBIDIUM module has got a setup to a basic configuration. The following guide describes the setups and enables you to find the configuration for your special environment. This example shows screen shots of the PC program tabs configuring a DI module. 1. Factory Settings : Start the configuration after a Reset of the module. Activate the Profile tap and select: Profile: Factory Settings Click on the OK button. 2. Select Functions: If Factory Settings has been applied, the following functions now are activated or deactivated ( VPS tab appears only if option V has been installed as well): To enable further functions click on the applicable Edit and/or Use check boxes.

11 Page WSS Parameter: Insert The WSS data are grouped in 4 data groups. Each group has its own window. The columns Window and Data Group indicate which group belongs to which window of the video inserter (please also refer to the Insert function). Click on the Text checkbox to switch between text format and bit format. Use the Visible checkbox to switch the window on or off. Auto Shut-Off In case no valid WSS data can be received, the display can be switched off automatically after a delay. In this case, a message appears instead of the text or bit format: Grouppe Meldung 1 WSS ASPECT RATIO:? 2 WSS ENHANCED SERVICES:? 3 WSS SUBTITLES:? 4 WSS OTHERS:? The delay can be selected in the range of 2 10 seconds. This auto switch-off can be deactivated. GPI Auto Switch-Off In case no valid WSS data can be received the GPI signal outputs can be switched to inactive state with the selected delay.

12 Page 12 Decoder It is possible to adjust some parameters of the WSS decoder if decoding of WSS data out of line 23 is required. This set-up has no relevance if WSS data will be decoded out of an Ancillary Data Packet. Auto Threshold The WSS data threshold can be adapted automatically to the video and data level. Manual Threshold Value While Auto Threshold has been deactivated, the threshold value can be adjusted manually. This way it is possible to find out the limits of the threshold. Decoder Parameter The current values of four additional parameters are shown in the Sample, Length, Centre and Start windows. These parameters should be adjusted once automatically. Click the Auto Adjust button to start the auto-adjust procedure. The procedure will last about 14 minutes. A click on the Reload Page button (beneath the tab) refreshes all parameters on this tab; this enables to monitor the changes at the parameters. The Adjusting Parameters checkbox as well as the WSS ADJUST lamp indicate the run status of the procedure. The procedure will be finished automatically, the best parameters has then been found and stored.

13 Page Adjust the Video Windows: The video window can be adjusted according to your needs. The windows 11 to 14 have been reserved for the four WSS data groups. XI modules have a digital video channel for SD and HD video formats. XI adjusts position and size of all visible windows automatically according to the applied video format. All calculations will be referenced to that video format which is present during last set-up at Insert tab. It is recommended to choose the video format with least number of lines during set-up. Examples: If you are working with SD and HD video formats, apply SD video during set-up. If you only switch between an HD 720 format and an HD 1080 video format, apply HD 720 format during set-up.

14 Page LEDs, Lamps and GPI: The following functions for the LEDs are provided: WSS Signal LED lights up as long as valid WSS data can be received. WSS Data Received LED lights up as soon as valid WSS data could have been decoded once after power-on. The following functions for the lamps are provided: WSS Signal WSS Auto Adjust Lamp lights up as long as valid WSS data can be received. Lamp lights up indicating that the auto-adjust procedure is running. The following functions for the GPI outputs are provided: WSS Aspect Ratio bit 0 WSS 4:3 WSS Aspect Ratio bit 1 WSS 14:9 WSS Aspect Ratio bit 2 WSS 16:9 WSS Letterbox WSS Subtitles WSS Surround Sound Please refer to the chapter GPI Signal Outputs: Programmable Functions.

15 1.4 GPI Signal Outputs: Connection Option W WSS Decoder Page 15 There are four GPIs (General Purpose Interfaces) located at DSUB9 female connector GPI/LTC IN at the rear panel of the module. Basically each GPI (GPI_1 to GPI_4) can be an input or an output. Further a relay contact (GPI_5) can be assigned for an output feature. The relay connects to GND on its active state. Alpermann+Velte 1 SERIAL DSUB9 1: GPI_1 2: GPI_2 3: GPI_3 4: GPI_4 5: GND 1 GPI relay DSUB9 5: GND 7: GPI_5 1.5 GPI Signal Outputs: Programmable Functions The following functions for the GPI outputs are provided. A description of each individual WSS bit is given in the chapter Information Content of WSS Data Bits. WSS Aspect Ratio bit 0 WSS Aspect Ratio bit 1 WSS Aspect Ratio bit 2 WSS 4:3 WSS 14:9 WSS 16:9 WSS Letterbox Direct output of the bit values of b0, b1 and b2 (group 1). The aspect ratio can then be decoded according to the table in the chapter Information Content of WSS Data Bits. Aspect ratio 4:3 detected. Bits b0, b1 and b2 (group 1) will be evaluated. GPI becomes active if the bit combination equals to 000. Aspect ratio 14:9 detected. Bits b0, b1 and b2 (group 1) will be evaluated. GPI becomes active if the bit combination equals to 100 or 010 or 011. Aspect ratio 16:9 detected. Bits b0, b1 and b2 (group 1) will be evaluated. GPI becomes active if the bit combination equals to 110 or 001 or 101 or 111. Letterbox format detected. Bits b0, b1 and b2 (group 1) will be evaluated. GPI becomes active if the bit combination equals to 100 or 010 or 110 or 001 or 101. WSS Subtitles Bit 8 (group 3): GPI becomes active if bit 8 = 1. WSS Surround Sound Bit 11 (group 4): GPI becomes active if Bit 11 = 1. After power-on, the GPI outputs remain inactive until valid WSS data can be decoded. Having GPI Auto Switch-Off enabled, the GPI outputs become inactive again if the WSS data input fails except the GPI output directly reflects the state of a bit. Having GPI Auto Switch-Off disabled, the GPI output will remain its last state until a new state can be decoded.
